At its most basic, copyright is an aspect of the law that grants the person or entity who holds the copyright to a work exclusive rights to that work for a limited amount of time. Subject to certain limitations, it is illegal for anyone to infringe upon those exclusive rights without obtaining permission from the copyright owner.
From Title 17, Chapter 1, Section 102 of the U.S. Code:
Copyright protection subsists, in accordance with this title, in original works of authorship fixed in any tangible medium of expression, now known or later developed, from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. Works of authorship include the following categories:
Copyright protection does not extend to (again from Section 107 of the U.S. Code):
To summarize, any original work of authorship is copyrightable, but facts and concepts are not.
See 17 U.S.C. §§ 102, 103, and 105 in Links and Recommended Readings for more information.
In most cases, the creator of the work is automatically the copyright holder, unless that person or group elects to transfer the copyright to another entity. An important exception to this is works made for hire.
A work made for hire is defined in Title 17, Chapter 1, section 101 of the U.S. code as:
“a work prepared by an employee within the scope of his or her employment, or a work specifically ordered or commissioned for use as a contribution to a collective work.”
In these instances, the employer is automatically the copyright holder. Like many non-for-profit educational institutions, pursuant to the Rosalind Franklin University of Medicine and Science Policy on Intellectual Property, Tangible Research Property and Commercialization of Such Properties, RFUMS chooses to forgo this right in some instances. See Works Made for Hire and the Rosalind Franklin University of Medicine and Science Policy on Intellectual Property, Tangible Research Property and Commercialization of Such Properties in Links and Recommended Readings for more information.
More than likely, yes! If you have ever created a copyrightable work, as is defined in From Title 17, Chapter 1, Section 102 of the U.S. Code, and you have not transferred the copyright or created a work for hire, than you automatically own a copyright!
From Title 17, Chapter 1, Section 106 of the U.S. Code, subject to certain limitations, a copyright owner has the exclusive rights to do and to authorize any of the following:
So if you want to do something with a copyrighted work that is an exclusive right of a copyright owner, you must either:
